To ALL WHoM Ir MAY coNcEEN:

VBe it known that I, CHARLES ALLEN, of Petersburg, in the. county of Menard, and State of Illinois, have invented a new and useful Device for Hanging-lVindow-Sashes; and Ido hereby declare that the following is a full and clear description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The natureoi' this invention consists in an improved method of hanging the upper and lower sashes of a window by'means ofva single oord passingover a stationary pulley at the top of the frame, the two sashes being' attached to the opposite ends of the same cord and arranged to balance each other. This much of the device is, I am aware, not new, but it is rendered available and perfectly adapted to the `purpose for which it is intended'by an arrangement for tightening the cord and adjusting it in snchamanner as to keepboth sashes in their proper relative positions. Ifrovision is also made for closing the lower portion of the window tightly, while the top part is opened slightly for ventilation.

To enable those skilled' in the art to make-and use my improved windows, I will proceed,v to describe their construction and operation.

- Figure 1 of the drawings is a front elevation of the window complete.

Figure 2 is a sectional transverse elevation. l

Figure 3 is an elevation of the tightener. l v

The sashes and B are tted into grooves in the frarne C, as usual, and are connected togetherby a cord, a, attached to the top of each sash, and passing thence over a pulley or sheave, a', on top of the frame. The sash A has a tghtener, 1J, as shown more clearly in iig. 3, to which the cord isattached. When the loosening of-the cord requires its readjustment thistigh'tener may be used for that purpose by simply turning the nut b either up or down until rboth sashes are properly arranged. The tightener b may be a simple screw eyelet-pin passing down through the wood of thesash, and having its nut b of such a size and so arranged as to present its edge through a mortise cut in the face of the sash-stile for it, and it -may there be operated by a persons thumb and ngers.- It will of course bejudicious to place Washers on the pin of each side of the nut b. A piece'of wood, C', hinged to the frame at .c, may be folded up into the pocket prepared to receive it in the side of the frame, when both sashes are t'o be opened or closed, but when it is requiredA to close the bottom portion of the window while the top is left open for ventilation this piece should be thrown down upon the sill under the sash, as shown in g. 1. v l

Having described my invention, what I cla-im, isl, i

The tightener b b', when applied to the cord a of the sashes A B, substantially as described and set forth.

I also claim the Ventilating-piece C applied to theframe C, in combination with the self-balancing sashes A B and cord-tightener b b', substantially inthe manner and for the purpose set forth.

' CHARLES ALLEN.
